Just to be anal - you CAN have mutually exclusive arguments - but you
have to run the code yourself. For example:
<cffunction name="foo" returnType="string" access="public">
<cfargument name="alpha" type="numeric" required="false">
<cfargument name="beta" type="numeric" required="false">
<cfif isDefined("alpha") and isDefined("beta")>
<cfthrow You get the idea
